BLUE-PRINT WASHING AND DRYING MACHINE.

Specification of Letters Patent.

Patented Get. 19, 19I1.

Application filed August 27, 1910. Serial No. 579,258.

To all whom it may concern:

Be it known that I, OSCAR Hoors, a citizen of the United States, and a resident of the city of New York, borough of the Bronx, in the county and State of New York, have invented a certain new and Improved Blue-Print Washing and Drying Machine, of which the following is a full, clear, and eXact description.

My invention relates to blue print washing and drying machines, and it has for its object to provide one having two endless belts, having sprocket openings at their sides, which are disposed against each other, and which run over rollers with sprocket teeth j ournaled in a casing containing tanks, and a compartment for respectively washing and drying the blue prints. The blue prints are conveyed between the belts through the machine, and are introduced and removed at points outside the casing where the belts are spaced from each other.

Another object of the invention is to provide a tank in which rollers are disposed to rotate, a wringer being mounted on the tank through which the belts disposed over the rollers travel as they leave the tank, there being means for adjusting the members of the wringer. Pipes are disposed below the wringer for conveying water to the belts and the blue prints disposed therebetween.

Additional objects of the invention are to provide means for holding the belts taut, and means for regulating the speed of the belts through'the machine.

Still other objects of the invention will appear in the following complete descrip- The preferred form of my invention is illustrated in the drawings, and described in this specification. I

In the drawings similar reference characters refer. to similar parts in all the views, in which Figure l is a sectional elevation of the invention; Fig. 2 is a transverse sectional view of Fig. 1; Fig. 3 is an enlarged fragmentary view showing the means for keeping the belts taut; Fig.4 is an enlarged fragmentary view showing the means for adjusting one of the wringer members relatively to its companion wringer member; Fig. 5 is an enlarged fragmentary view showing one side of one of the belts; and Fig. 6 is a view showing the sprockets on one of the rollers engaging the openings at one of the sides of the belts.

By referring to the drawings it will be seen that a frame 5 is provided which is supported on legs 6, there being two tanks 7 in this frame 5, which are divided by a partition 8. Disposed above the tanks 7 on members 9 of the frame 5, there is a heating compartment 10. J ournaled in bearings in the central members 9 there are two wringer members 11, which are spaced from each other. In the projecting portions 19 of the frame 5, at the right of the tanks, there are slots 12, in which are disposed bearing members 13, in which are j ournaled studs 14, secured to a wringer member 15. This wringer member 15 is adapted to coact with a wringer member 16, the studs 17 of which are journaled in the frame 5. Screws 18 are disposed in threaded orifices in the ends of the projecting portions 19 of the frame 5, these screws being disposed against the bearing members 13 to press the wringer, member 15 in the direction of its companion wringer member 16. In each'of the tanks 7 there are two sets of rollers 20, which are journaled to the sides of the tanks. There are also tw6 additional rollers 21 journaled to the sides of each of the tanks, and

a roller 22 is journaled to the left-hand members 9 of the frame. Below the bottom of the compartment 7 there are two rollers 23 journaled at the frame 5, one to the ex 'treme right, and the other to the extreme left. In the bottom of the compartment 10 there is an opening 24, there being also an opening 25 in the left-hand side of the com- I partment near its top. Rollers 26 are journaled in hearings in the side of the compartment 10. In the projecting portions'27 of the left-hand members 9 of the frame 5, there are slots 28, in which are disposed bearing members 29 in which shafts 30 and 31 are journaled. Screws 32 are provided which mesh in threaded orifices in the ends handtank 7., around the rollers 20 of the said left-hand tank, and under the righthand roller 21 in the said tank. The belts are -led. between the wringer members 11 over the rollers 20 and 21 in the right-hand tank and between the wringer members 15 and 16. The belts are then disposed upwardly through an opening 37 in the drying compartment, one of the belts being led upwardly and to the right, over the rollers 38, thence downwardly through the opening 24 and under the rollers 23; the other belt being led out through the openings 25 and over the roller. One of the belt-s is thus led downwardly and the other led upwardly at the left of the frame, and these belts are disposed over the rollers 33 respectively, and thence over the roller 22, as has been described. These belts are two in number and through the tanks and through the greater portion of the drying compartment 10, they are disposed one over the other so that they may convey between them the blue prints which are to be washed and dried.

The belts 36-are manufactured of light material, through which the water may readily penetrate, and, if desired, openings may be made in the belts to permit the water to reach more freely the blue prints disposed therebetween.

To the wringer members 16 is connected a stud 40, which projects beyond the frame, a sprocket wheel 41 beingisecured to said stud. This sprocket wheel 41 is connected to a sprocket wheel 42, by means of a sprocket chain 43, the sprocket wheel 42 being mounted on a shaft journaled in a bearing member 44. A second shaft 46 is journaled in this bearing member, a disk wheel 46 and a pulley 47 being secured to the said shaft 45. A disk 48 is secured to the shaft, to which the sprocket wheel 42 .is secured, these disks 46 and 48 being connected by a friction member 49 which rotates freely on the stud 50, the stud being'threaded and meshing in a threaded orifice 51 in the bearing member 44 It will be seen that as the axes of the disks 46 and 48 are spaced from and are parallel to each other, the speedof. the sprocket wheel 42 may 'be regulated by moving the stud 50 to the right or to the left, as may be desired, the friction member 49 being thereby moved relatively to the disks 46 and 48, with which it contacts. 55

As the wringer member 16 is rotated, moves the belts 36 upwardly, at the right of the frame, the belts being drawn over the rollers 33 and over the roller 22 into the lefthand tank 7. The blue prints which are tov hand tank 7, an then between the wringer removed from the machine.

members 15 and 16, the pipes 52 being provided, with their terminals disposed one on each side of the belts 56 and just below the wringer members 15 and 16, so that the belts with the blue prints therebetween will be washed with-fresh water before they are conveyed between the wringer members 15 and 16. The belts 36 move upwardly through the opening 37 into the drying compartment 10, and the blue prints are subwardly over the rollers 38 and the other belt is led downwardly over the roller 39,

and at this point where the belts are separated from each other, the blue prints are The rollers 33 may be moved to the left by means of the screws 32, so that the belts 36 will be kept taut at all times.

Having thus described my invention, I claim as'new and desire to secure by Letters Patent drying compartment, two belts, one disposed over the other for traveling on the rollers, the belts being led upwardly from the tank to the drying compartment through one of the said slots in the bottom thereof, one of the belts being led down through the other slot in the bottom of the drying compartment, the other belt being led out of the drying compartment through the opening in its side, both belts returning to the said series of rollers.
